You need to change the Solution Platform from "Any CPU" to "x86". The steps are given below:

  1. Right click on the Solution File in Solution Explorer:

  2. Click on the Configuration Manager.
  3. Click on the Active Platform Drop down, if x86 is already there then select that, else click on New.
